It should be in the tetenal manual anyway.
The drop in quality isn't immediate after the developer begins to exhaust, once you don't like the results, extend your dev time.
Not sure if im just blind but im holding the manual in my hands right now and it says nothing about this? But adding 30 seconds after 4-5 rolls works for you? and then adding 2 minutes to the blix?
